    <p>I am struggling with converting a LINQ statement which returns an anonymous type to an ObservableCollection with a custom class, I'm happy with the LINQ statement, and the class definition, the problem (I think) is to do with how I am implementing the IQueryable interface between my anonymous type and the class itself.</p> <pre><code>public class CatSummary : INotifyPropertyChanged { private string _catName; public string CatName { get { return _catName; } set { if (_catName != value) { _catName = value; NotifyPropertyChanged("CatName"); } } } private string _catAmount; public string CatAmount { get { return _catAmount; } set { if (_catAmount != value) { _catAmount = value; NotifyPropertyChanged("CatAmount"); } } } public event PropertyChangedEventHandler PropertyChanged; // Used to notify Silverlight that a property has changed. private void NotifyPropertyChanged(string propertyName) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); //MessageBox.Show("NotifyPropertyChanged: " + propertyName); } } } private void GetCategoryAmounts() { var myOC = new ObservableCollection&lt;CatSummary&gt;(); var myQuery = BoughtItemDB.BoughtItems .GroupBy(item =&gt; item.ItemCategory) .Select(g =&gt; new { _catName = g.Key, _catAmount = g.Sum(x =&gt; x.ItemAmount) }); foreach (var item in myQuery) myOC.Add(item); } </code></pre> <p>The error I am getting is on the last line and is<br> <code>"Argument 1: cannot convert from 'AnonymousType#1' to 'CatSummary'"</code></p> <p>I'm relatively new to c# and need pointing in the right direction - if anyone has any tutorials on this sort of thing that would help as well.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
